The structure ontology (see http://www.jeromedl.org/ontology/2.1/ for more information) is used at the bottom layer (classic services and metadata) of JeromeDL architecture (see Sec. 7.2). It is used to handle typical tasks required from a digital objects repository, i.e., it keeps track of the physical representation of resources, their structure and provenance. The structure ontology provides means for a flexible and extendable electronic representation of objects. Such flexibility is especially significant in expressing relations to other resources.

Modern digital library systems not only store the bibliographic metadata but also the electronic representation of the content itself. Depending on its type, the content typically follows some structure, e.g. we can decompose a book into chapters and provide individual descriptions for each chapter with information about relations between them. Including structural concepts in ontologies and using these concepts in metadata descriptions provides a universal layer for metadata and content retrieval. It supports extending the structure description with new concepts, without violating the integrity of existing data. The application of ontologies for structural descriptions enables uniform access to structural and bibliographical information (212,197).

JeromeDL cross-reference: Classes and Properties

JeromeDL structure ontology introduces the following classes and properties:

Class: jeromedl:BinaryResource

This is an information object which has a binary representation, such as JPG, PDF, etc. NOTE: meta-information extracted from the resource (e.g., EXIF) should be directly bound to this resource, not through some additional properties (e.g., hasExif), unless the ontology related to this binary resource does not support such direct binding.
